Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF13-5P-1.25V(50) is determined by the following critical parameters that must remain constant:

• Connector Series: DF13 (ensures mechanical and electrical compatibility within the product family)
• Number of Positions: 5 (maintains pin count and mating interface)
• Pitch - Mating: 0.049" (1.25mm) (ensures proper spacing and contact alignment)
• Contact Type: Male Pin (preserves mating interface polarity)
• Mounting Type: Surface Mount (maintains PCB assembly compatibility)
• Current Rating: 1A (ensures electrical capacity)
• Voltage Rating: 150V (maintains electrical safety margins)
• Operating Temperature Range: -35°C ~ 85°C (preserves thermal operating envelope)
• Termination: Solder (maintains assembly process compatibility)
• Fastening Type: Detent Lock (ensures mechanical retention method)

The DF13-5P-1.25V(76) qualifies as a direct substitute based on these parameters. The primary difference is the shrouding configuration (3 Wall vs. 4 Wall) and product status transition from obsolete to active, along with enhanced post-contact finish specification.

Parameter Comparison

Engineering Selection Recommendations

The DF13-5P-1.25V(76) is the direct substitute for the obsolete DF13-5P-1.25V(50). Selection of the substitute is based on the following engineering factors:

Product Status: The DF13-5P-1.25V(76) maintains active product status with current manufacturing support, ensuring long-term availability and supply chain continuity compared to the obsolete DF13-5P-1.25V(50).

Compliance and Certifications: The DF13-5P-1.25V(76) carries ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement. Both parts maintain UL94 V-0 flammability rating and identical electrical specifications.

Mechanical Compatibility: Both connectors share identical electrical and thermal parameters. The shrouding difference (3 Wall vs. 4 Wall) represents a design variation within the DF13 series that does not affect core mating interface or electrical performance. The substitute maintains all critical dimensions including insulation height, contact geometry, and pitch specifications.

Packaging and Availability: The DF13-5P-1.25V(76) is supplied in tube packaging with significantly higher inventory availability, supporting production requirements and reducing lead time risk.

Frequently Asked Questions (FAQ)

Q: Can the DF13-5P-1.25V(76) be used as a direct replacement for the DF13-5P-1.25V(50) in existing designs?

A: Yes. Both connectors share identical electrical ratings (1A, 150V), operating temperature range (-35°C ~ 85°C), pitch (0.049" / 1.25mm), position count (5), and core mechanical interface specifications. The mating interface is fully compatible.

Q: What is the difference between the 4 Wall and 3 Wall shrouding configurations?

A: The shrouding configuration refers to the number of walls in the connector housing. Both configurations maintain the same mating interface, electrical performance, and mechanical retention. The 3 Wall configuration in the DF13-5P-1.25V(76) is a design variant within the DF13 series that does not affect functional compatibility.

Q: Why is the DF13-5P-1.25V(50) listed as obsolete?

A: Product obsolescence indicates that the manufacturer has discontinued active production and support for this specific part number. The DF13-5P-1.25V(76) represents the current active equivalent within the DF13 product family.

Q: Are there any compliance differences between the two parts?

A: The DF13-5P-1.25V(76) includes explicit ROHS3 compliance and REACH unaffected status documentation. Both parts maintain UL94 V-0 flammability rating. The substitute meets current regulatory requirements for electronic component procurement.

Q: What is the packaging difference, and does it affect component selection?

A: The DF13-5P-1.25V(50) packaging is not specified, while the DF13-5P-1.25V(76) is supplied in tube packaging. Tube packaging is standard for surface mount connectors and supports automated assembly processes. This difference does not affect electrical or mechanical compatibility.

Q: Are the contact finish specifications identical?

A: Both parts specify gold contact finish on the mating surface at 8.00µin (0.203µm) thickness. The DF13-5P-1.25V(76) additionally specifies gold finish on the post contact with matching thickness, providing enhanced specification documentation.
